Connection TCP/IP over SSH fails in Workbench 6.2.4 on Windows 7 64 bit

I have been trying to connect to MySQL remote server from my Windows 7, 64-bit machine and it fails with authentication error.

Please:
1 Check that mysql is running on server 127.0.0.1
2 Check that mysql is running on port 3306 (note: 3306 is the default, but this can be changed)
3 Check the agi has rights to connect to 127.0.0.1 from your address (mysql rights define what clients can connect to the server and from which machines)
4 Make sure you are both providing a password if needed and using the correct password for 127.0.0.1 connecting from the host address you're connecting from
